External Type 2
External routes are those imported into OSPF from other routing protocol or processes. OSPF computes
the path cost differently for external type 1 and external type 2 routes. The cost of an external type 1
route is the cost advertised in the external LSA plus the path cost from the calculating router to the
ASBR. The cost of an external type 2 route is the cost advertised by the ASBR in its external LSA.
NOTE:
The following example uses the CLI to configure OSPF. You can also use the Web interface. Click
Routing >
OSPF
or
IPv6 > OSPFv3
in the navigation tree.
